The independent auxiliary storage pool (IASP) provides the ability to group disk units together that can then be taken off-line or brought on-line independent of the system ASP. This document outlines the steps to create an IASP. There may be some restrictions and/or pre-requisites required before running these steps and it is recommended to check the relevant IBM documentation.
Creating an IASP
To create an IASP, you must have at least one non-configured disk available on your Kyndryl Cloud Uplift LPAR. If you do not have a non-configured disk, you will need to first add a disk with the LPAR shutdown.
The Kyndryl Cloud Uplift reference link at the end of this document shows how to accomplish this.
Once the disk with appropriate size has been added via the Kyndryl Cloud Uplift UI, the IASP can be created using CFGDEVASP.
Configuring an IASP
- Run CFGDEVASP
- Enter the device name of the ASP and action type (*CREATE), press <ENTER>
- Select the ASP type (e.g. *PRIMARY, *SECONDARY), press <ENTER>
- Optionally select Protection, Encryption; leave Disk units at *SELECT, press <ENTER>
- If the disk was added successfully via the Kyndryl Cloud Uplift UI, you should see an non-configured disk to use
- Enter 1 for any disks you want to add to the IASP
- Confirm the disk as well as the size, press <ENTER>
- The IASP will then be configured and you should see the progress being displayed. This may take some time depending on the size of disk you created
- Wait for the message "Configure device ASP *CREATE request completed" displays
You can then vary on the device using
WRKCFGSTS CFGTYPE(*DEV) CFGD(IASPname)You can check the status of the ASP by running
DSPASPSTS ASPDEV(IASPname)
